I have one. its pretty neat. doesn't put out much light, probably less than a good chemstick, but on the other hand you don't have to worry about the foil wrapper getting punctured, and it can be reused if you use rechargable batteries (NiMH seems to be the hot ticket in rechargables).

depends on your uses. I got one for use as a low-output general camp light, so its great for that. unless you get some AA lithium batteries (Eveready makes some, though very hard to find) you'd have to worry about battery discharge if you intended to use one for an emergency light.

I've been meaning to get a couple of these. There are two levels of brightness avialable. You can choose between 180° or 360°, and there are a variety of colors. The brighter model in 180° in certain colors (I don't remember which), should be pretty bright. BTW the batteries to use are AA lithiums.

I've got a 180 deg. standard, and it's a nice little light. I bought the white, but it's really a pale greenish/bluish/white color. It's not as bright as I thought it would be, but it fills a tent well enough, and works well as a small area light or location marker. It's hard to read with, but the Extreme model is beter suited for that. I appreciated the longer runtimes of the standard over the Extreme. Rechargable AA's would most likely be the ticket, as there are small panel rechargers available to set on a rock or picnic table in camp.

Lithium AAs cost several times as much as Alkalines. They also last several times longer, weigh next to nothing & are almost uneffected by cold which would completely kill standard batteries. I'm a photographer & my equipment eats batteries like there's no tommorow. I use rechargable ni-cads for economy but when it has to have juice lithium AA are incredible! I think that using lithiums in the 50hr Extreme should provide longer run times than Alkalines in the 120(?)hr Standard. Oh yea, green is the brightest, by 1/3 if I remember right. I think I'll go see if REI.com has them. If you want more info, I dug up this link [url]http://www.equipped.com/krill.htm[url]

The Krill is about the brightness of a 12 hour chemlight stick after 1-1.5 hours of use. However, the Krill maintains that brightness for considerably longer than the chemlight. Here's the link to the large version of the chart NASA created in evaluating them for space useage.http://www.kriana.com/glowstick_ligh...comparison.jpg

If you want to use it for reading, you'll probably get a headache but the best one to use is the Green Extreme 180, the brightest of all variations. Used as a marker, you can see it from a hundred yards without much difficulty. In order of color brightness it runs from the "dimmest" of Red, Orange, Yellow, Purple (NEW), White, Blue, and Green as the brightest. In model order, it runs from the Krill (standard) 360º, Krill (std.) 180º, Krill Extreme 360º (rough tie with brightness of Krill (std.) 180º) and lastly the Krill extreme 180º. The Standard burns for 120 hours on standard AA's- longer on lithiums (and brighter for longer), whereas the Extremes burn for 50 hours of useable light(same notation re:lithium. All that burntime vs. the 12 hours you get with the chemlight(which is more like 6 hours useable time).

These are tough little suckers- they are great for fishing (if you can use lights with your bait- check local laws), they bounce off rocks nicely and stay intact/work, are waterproof to 150', etc. The velcro on the 180's is great for sticking it to things- like scuba tanks, motorcycle gas tanks, fleece jackets...

Sales have overwhelmingly favored brighter v. duration- both mine and the factory's. Green is the biggest seller as well- fairly evenly mixes of the 180 and 360. Maybe this will provide another perspective.
